Sounders FC - A Storybook Season
If you bleed rave green and have 27+ minutes on your hands this video is for you. Unless you, quite literally, have green blood; in that case you should use the spare time to see a physician.
But assuming you are in good health, check out this documentary on the Sounders first season. It's pretty good stuff providing you are not a Portland or Vancouver fan. Watch it or Kasey Keller will come to your house to talk metal all night. Wait, that might be kind of awesome actually.
